近年来，可再生能源在世界市场（特别是在西班牙能源市场）和社会中逐渐占据重要地位;这一事实表明，需要增加和改善对这些能源的了解。从一个多兆瓦级风力涡轮机的生命周期评估（LCA）的结果开始，这项工作的目的是评估在其发展过程中所做的不同选择的相关性。为了始终涵盖尽可能多的选项，我们分析了四种情景，重点关注生命周期的四个主要阶段：维护、制造、拆卸和回收。这些设想方案有助于评估所制定的生命周期评估因所作选择而产生的不确定性程度，但不包括因所用环境模型的不准确性和简化或不同参数的时空变异性而产生的不确定性。这项工作一直使用生态指标99 LCA方法进行。
During recent years renewables have been acquiring gradually a significant importance in the world market (especially in the Spanish energetic market) and in society; this fact makes clear the need to increase and improve knowledge of these power sources. Starting from the results of a Life Cycle Assessment (LCA) of a multi-megawatt wind turbine, this work is aimed to assess the relevance of different choices that have been made during its development. Looking always to cover the largest possible spectrum of options, four scenarios have been analysed, focused on four main phases of lifecycle: maintenance, manufacturing, dismantling, and recycling. These scenarios facilitate to assess the degree of uncertainty of the developed LCA due to choices made, excluding from the assessment the uncertainty due to the inaccuracy and the simplification of the environmental models used or spatial and temporal variability in different parameters. The work has been developed at all times using the of Eco-indicator99 LCA method.
